For the last month or so, the features of "define", "simplify" are not working on my adobe acrobat mobile, while it works fine on Windows version. Every time I ask it to "define" a selected word, it returns unrelated explanation. How to fix that?

Hi there

Hope you are doing well, and thanks for highlighting this.

Would you mind sharing the version of the Acrobat App and the device (Android, iOS) OS you are using?

Is this an issue with a particular PDF file or with all the PDFs? Try with a different PDF file and check.

Also, share a small video recording of the steps you are taking and the issue as it occurs, or a screenshot from both the Mobile app and the desktop app, so we can take it further with our development team.
